Revision of the Passive Voice
被动语态专项复习
复习目标
1. 复习被动语态的基本概念及结构。
2. 掌握一般现在时、一般过去时、一般将来时、含有情态动词的被动语态的用法。
Zhang Yu makes the bed
The bed is made by Zhang Yu
主动语态
active voice
被动语态 passive voice
一.知 识 回 顾
语法探究
何时使用被动语态:
1.
不知道谁是动作的执行者要用被动语态
This phone is made in Japan .
2.没有必要指出谁是动作的执行者时要用被动语态.
English is spoken in Britain.
3.只需强调动作的承受者时要用被动语态。
The bridge was built in 1990.
主动语态变被动语态的方法:
I speak English
主动语态:动作执行者+谓语动词的主动形式+动作的承受者
English is spoken by me
被动语态:动作的承受者+谓语动词的被动形式+by+动作执行者
说明(1)要将主动语态中的宾语变为被动语态的主语。(若主动句中的宾语为人称代词,要将宾格变为主格)。
(2)谓语动词变为相应的被动形式。(be done)
(3)把主动句中的主语变为被动句中的宾语,主格变宾格,并由by引导。
不同时态被动语态的构成:
一般现在时: am/is /are + done
1. We plant trees every spring.
Trees are planted (by us) every spring.
一般过去时: was/were + done
2. We planted trees yesterday.
Trees were planted (by us) yesterday.
一般将来时: will + be + done
3.We will plant trees tomorrow.
Trees will be planted (by us) tomorrow.
含情态动词: 情态动词+be + done
4.We can plant trees in spring.
Trees can be planted (by us) in spring.
